How the Drug Works:
Ipratropium blocks the action of the chemical transmitter acetylcholine.
Acetylcholine causes the muscles around the bronchial tubes to spasm and constrict, which makes it harder to breathe. By blocking acetylcholine, ipratropium allows these muscles to relax, widening the bronchial tubes (bronchodilation) and allowing more air into the lungs.
Albuterol dilates (opens) the bronchial tubes of the lungs by relaxing the muscles around the bronchial tubes. This allows for easier air flow into and out of the lungs. It also assists in removing (expectorating) mucus and other debris causing congestion in the lungs.
Uses:
To treat bronchospasm in patients with chronic obstructive pulmonary disease (CaPO) who are on a regular inhalant bronchodilator but continue to have symptoms of bronchial tube spasm.
Precautions:
Pregnancy: There are no adequate and well-controlled studies in pregnant women. Use only if clearly needed and the potential benefits out-weigh the possible hazards to the fetus.
Breastfeeding: It is not known whether ipratropium/albuterol appears in breast milk. Consult your doctor before you begin breastfeeding.
Children: Safety and effectiveness in children have not been established.
